Reve Medaka

Reve Medaka key facts

Care level

Intermediate

Lifespan

2-3 years

Size

About 3-4 cm (wild medaka reach up to 4 cm SL: FishBase)

Diet

Omnivore (floating prepared foods, live foods such as daphnia)

Container & Tank

The large fins look best from the side in a glass tank; avoid sharp décor and strong currents that could damage them.

Breeding

Fin extension and tasselling vary; choose breeders whose tails are well extended.

Tank Mates & Compatibility

Peaceful and fine with other medaka of similar size. To keep the variety's traits, do not let it breed with other varieties in the same container.

Diet & Feeding

Give floating food that is eaten within 3-5 minutes: at least twice a day in summer, once a day in spring and autumn, and little or none outdoors in winter.

Cautions

Never release ornamental medaka into rivers, ponds or paddies; hybridisation causes genetic pollution of wild medaka.

About Reve Medaka

Reve medaka: an Aomiyuki-type body with long, flowing fins and a morpho-style effect. Small, intermediate difficulty. The name means dream in French.

7 things to know before welcoming a Reve Medaka

1. 1Long fins on an Aomiyuki base

   Reve has an Aomiyuki-type body with fin luster and a morpho-style effect, and its fins grow noticeably long, including the soft rays of the tail fin. The flowing fins look best when viewed from the side. That length also means it needs somewhat more careful care than a standard medaka.

2. 2Keep the current gentle

   Long fins can tear in a strong current, and constantly swimming against it may tire the fish. Turn down the filter outflow or aeration and leave a calm area in the tank. Fitting a sponge over the intake also helps keep the fins from being sucked in.

3. 3Choose tank mates carefully

   Fish that nip fins or dart around quickly are poor companions. Calm medaka of a similar size, especially other long-finned types, are the safer choice. Once you mix them, also check that Reve is not being outcompeted at feeding time.

4. 4Small, regular water changes

   Sudden changes in water quality can leave fish unwell. Use dechlorinated water at a matching temperature, and change it in small amounts rather than all at once. Damaged fins are more likely to worsen in dirty water, so keeping the water clean matters.

5. 5Prevent missed meals

   Slow, graceful swimmers can lose out to quicker fish at feeding time. Offer small portions of a fine-grained food several times a day and remove leftovers promptly. Keep an eye on body condition so you notice early if the fish is getting thin.

6. 6Container and hiding spots

   Although small, Reve does well in a container with generous water volume, which keeps water quality steadier and gives the fins room to move. Avoid sharp decorations that could snag the fins, and provide cover with soft plants. The fin luster and morpho-style effect change with the light, so a container you can view from the side is a good choice.

7. 7Checks when it arrives

   When the fish arrives, float the sealed bag on the water to match temperatures, then acclimate it gradually. Check for torn fins, anything unusual on the body, and any problems with how it swims. If possible, keep it in a separate container for a while before introducing it to existing fish.

Frequently asked questions about Reve Medaka

Q.Can beginners keep Reve?

A.Reve is rated intermediate difficulty. Basic care is much like any medaka, but you need to manage water flow and choose tank mates with the long fins in mind. It is best to start once you are comfortable with medaka keeping, or to set up the tank carefully beforehand.

Q.How long does Reve live?

A.Reve typically lives about 2 to 3 years. It also varies with the environment and the individual, so stable water quality and temperature and appropriate feeding are the basics for enjoying the fish for as long as possible.

Q.Can Reve live with other medaka?

A.It usually goes well with calm medaka of a similar size. Fin-nipping or fast-moving tank mates can damage the long fins. After mixing them, watch the condition of the fins and how well Reve is eating for a while.

Q.How big does Reve get?

A.Reve is a small medaka, around 3 to 4 cm in total length, though individuals vary. Because the fins extend so far, the fish can look larger than these figures suggest.

Q.What if the fins get damaged?

A.First remove likely causes of the damage, such as strong current, aggressive tank mates or sharp decorations. Then keep the water in good condition and, if needed, let the fish recover in a separate container. If the problem continues, it is worth asking an experienced keeper or a specialist.
